In the Eastern Aegean lies an island of forested hills and olive groves, with streams, marshes and a lagoon that nearly cuts the land in two. It was here, over two thousand years ago, that Aristotle came to work. Aristotle was the greatest philosopher of all time. Author of the Poetics, Politics and Metaphysics, his work looms over the history of Western thought. But he was also a biologist - the first. Aristotle explored the mysteries of the natural world. With the help of fishermen, hunters and farmers, he catalogued the animals in his world, dissected them, observed their behaviours and recorded how they lived, fed, and bred. In his great zoological treatise, Historia animalium, he described the mating habits of herons, the sexual incontinence of girls, the stomachs of snails, the sensitivity of sponges, the flippers of seals, the sounds of cicadas, the destructiveness of starfish, the dumbness of the deaf, the flatulence of elephants and the structure of the human heart. And then, in another dozen books, he explained it all. In The Lagoon, acclaimed biologist Armand Marie Leroi recovers Aristotle's science. He goes to Lesbos to see the creatures that Aristotle saw, where he saw them, and explores the Philosopher's deep ideas and inspired guesses - as well as the things that he got wildly wrong. Leroi shows how Aristotle's science is deeply intertwined with his philosophical system and how modern science even now bears the imprint of its inventor.

Full of fascinating and bizarre cases of genetic mutation and irregularity, 'Mutants' is an amazing exploration of the human form in all its beautiful and unique guises. Why are most of us born with one nose, two legs, ten fingers and twenty-four ribs - and some of us not? Why do most of us stop growing in our teens - while others just keep going? Why do some us have heads of red hair - and others no hair at all? The human genome, we are told, makes us what we are. But how? Armand Marie Leroi takes us to the extremes of human mutation - from the grotesque to the beautiful, and often both at the same time - to explain how we become what we are. Through the tales of long-lived Croatian dwarves, ostrich-footed Wadoma tribesmen, sex-changing French convent girls, and many more wonders of human development, Leroi has written a brilliant narrative account of our genetic grammar and people whose bodies have revealed it.

Stepping effortlessly from myth to cutting-edge science, "Mutants" gives a brilliant narrative account of our genetic code and the captivating people whose bodies have revealed itaa French convent girl who found herself changing sex at puberty; children who, echoing Homeras Cyclops, are born with a single eye in the middle of their foreheads; a village of long-lived Croatian dwarves; one family, whose bodies were entirely covered with hair, was kept at the Burmese royal court for four generations and gave Darwin one of his keenest insights into heredity. This elegant, humane, and engaging book acaptures what we know of the development of what makes us humana ("Nature").

The remarkable but neglected story of Aristotle's founding role in the scientific study of nature Both a travelogue and a study of the origins of science, The Lagoon shows how an ancient thinker still has much to teach us today. Aristotle's philosophy looms large over the history of Western thought, but the subject he most loved was biology. He wrote vast treatises on animals, dissecting them, classifying them, recording how they lived, fed, and bred. He founded a science. It can even be said that he founded science itself. In this luminous book, acclaimed biologist Armand Marie Leroi recovers Aristotle's science. He explores Aristotle's observations, his deep ideas, his inspired guesses-and the things he got wildly wrong. Leroi visits the Aegean island where Aristotle plumbed the secrets of the living world in all its beauty. Modern science still bears the stamp of its founder. The Lagoon reveals that Aristotle was not only the first biologist, but also one of the greatest.
